teams resting their stars in big games, especially on TV. Basically if you want a quick fix, when you meet a team in the playoffs, you determine home series advantage for the series by head to head record during the regular season. If there is a tie, you default to the seed.

Its a simple fix that doesn't fix the entire problem, but it would make regular season games a bit more exciting, and teams wouldn't rest their players against good teams, only teams like the Nets, Lakers, etc. Obviously the real solution is shortening the season, but there is too much money to figure that out in the short run.
